Robert Griesemer 703974d608 go/types: rewrote instantiation of named types
A parameterized named type is in one of two states: not yet
instantiated, or instantiated. It may be instantiated with
any type, including (outer) type parameters. An instantiated
parameterized type may needs its type parameters substituted
if it is part of an enclosing type (or function) that is
instantiated.

A Named type has an extra field targs which is set to the
type arguments if the type is instantiated.

As a result, we don't need a representation for (partially)
instantiated parameterized types anymore: the Parameterized type
is now unused (but still present in the code).

Added a unique id field to TypeParam types so they can be
printed with a unique name. This permits the creation of a
unique type name for instantiated types which then can be used
for hashing that type name.

Also, made interfaces as type bounds work in more cases.

A handful of places (in testdata/map.go2, map2.go2) are broken
(commented out) and need investigation.
